The three of them were friends. Mitsuki, who secretly harbored feelings for Nanami, couldn't confess her love before the other two became a couple, leaving her to spend her days with complicated and frustrated feelings. One such day, driven by loneliness, Mitsuki decided to post her current troubles on an online love advice forum. There, she was recommended something called "hypnotism"...? The hypnotism she tried half-jokingly... gradually, her desires, now without brakes, began to change the two's relationship... A melting, ear-licking, brainwashing lesbian!
